FOUNTAIN-PEN.

SPECIFICATION forming part of Letters Patent No. 48,360, dated March 17,1891.

Application filed May 12, 1890. Serial No- 351,461. (No model.)

To a, whom it may concern.-

Be it known that 1, JOHN OLIPHANT, a citizen of the United States,residing at Toledo, in the county of Lucas, State of Ohio, have inventedcertain new and useful Improvements in an Automatic ReservoirPen-Holder, of which the following is a specification, reference beinghad therein to the accompanying drawings.

This invent-ion relates to certain new and useful improvements inself-filling automatic reservoir pen-holders wherein a com pressiblebulb is employed in connection with a pivoted or hinged piece to beactuated by the thumb or finger or other means to compress said bulb.

It has for its object, among others, to provide for the ready assemblingof parts, to provide for the regular and uniform flow of the ink to thepen-point, and to improve generally upon this class of devices.

Other obj eets and advantages of the invention will appear in thefollowing description, and the novel features thereof will beparticularly pointed out in the claims.

The invention is clearly illustrated in the accompanying drawings,which, with the letters of reference marked thereon, form a part of thisspecification, and in which Figure 1 is a side elevation, with parts insection, showing a pen-holder constructed in Fig. 2 is a top plan. Fig.3is aside elevation,with parts in section, with the pressure-leverdepressed, and showing a modified form of tongue or ink-flow regulator;and Fig. 4 is an end view with the pen removed.

Like letters refer to like parts in all the figures of the drawings.

Referring now to the details of the draw ings by letter, A designatesthe holder, which may be of any desired material, such as hard rubber,celluloid, or any other substances or material suited for this purpose,and of any preferred shape. It is formed with a cavity or chamber A toreceive the working parts of the holder. At the outer end I remove aportion of the body of the holder, as B, to permit of the insertion ofthe tube 0, the object of which is to take up and hold the ink. Afterthe tube has been inserted this portion B may be retained in place inany suitable niannersuch, for instance, as pins or rivets awhich willallow of its ready removal when desired.

\Vithin the chamber A there is located a compressible bulb D, of suchsize as will fit quite closely within the chamber, and at its outer endembracing the inner end of the tube 0, and held from movement endwise bymeans of shoulders I) Z), as seen best in Fig. 3.

E is a pressure-lever pivoted within an opening in the body of theholder upon a transverse pin or pivot c, and adapted when closed toconform to and complete the con.- tour of the body of the holder, asseen in Fig. 2. Its forward end is preferably beveled, as shown at d, soas to allow ready movement thereof, and is designed to be pressed inwardupon the bulb by the thumb or finger, as indicated in Fig. 3, tocompress the bulb.

F is the pen-point, which may be of any desired or well-known form ormake, and is inserted in a recess or opening 6 therefor in the forwardend of the holder beneath the tube O, its movement inward being limitedby the shoulder 12, as seen in Fig. 3.

In Figs. 1 and 2 I have shown the lower portion of the tube 0 as reducedvery thin to make a flexible tongue 6, which rests upon the end of thepenpoint, as shown best in Fig. 2, and as the end of the pen moves inwriting the tongue moves with it, and by this movement the ink. isworked down to the point of the pen asit is needed. This tongue alsoprevents waste or accidental flow of the ink when not required. In Fig.3 I have shown a different construction for this purpose. It consists ofa wire G or any other material inserted within the tube 0, with itsouter end bent downward and bearing upon the top of the pen near thepoint thereof.

In Fig. 1 I have shown a small piece of absorbent material II, assponge, which is held upon the pen in any suitable manner at the pointof the tube 0, so as to prevent the ink from squirting out over thepaper, and also preventing the ink from being drawn back into the tubewhen the pressure is removed.

The operation is simple and will be readily understood. The pen-holderis taken in the hand and pressure put upon the leverE with TOO eitherthe thumb or finger, and the pen-point and tube 0 then inserted. in theink until the ink covers the end of the tube. The pressure .is thenremoved from the lever and the ink flows up into the tube and through itinto the bulb, when the pen is ready for writing. Little or much ink maybe taken up, as preferred, and an independent filler is not required.

What I claim is l. The combination, with the holder provided with acavity and a removable portion at the forward end thereof, of the tubearranged beneath the removable portion, the compressible bulb within thecavity of the holder and sleeved upon the inner end of the tube, and thepivoted pressure-lever pivoted to the holder and arranged in line withthe bulb to compress the same, substantially as shown and described.

2. he combination, with the holder, of the tube, the compressible bulb,and the flexible tongue arranged to bear upon the pen near its point,substantially as and for the purpose specified.

3.- The combination, with the holder and the compressible bulb andpivoted pressurelever, of the tube held within the holder and having itsouter end reduced and adapted to bear upon the pen near its point,substantially as and for the purpose described.

at. In a reservoir pen-holder, the combination, with the holder having aremovable por tion and formed with interior shoulders Z) l), of the tube0, held Within the holder, and the compressible bulb within the holderwith its outer end embracing the inner end of the tube, and held frommovement outwardly by said shoulders, substantially as shown anddescribed.

In testimony whereof I aflix my signature in presence of two witnesses.
